Abstract
An attenuator for pressure and sound energy pulsations, such as are commonly produced in refrigerant gas discharged from a piston-type refrigerant compressor, is provided. The attenuator includes an annular elastomeric body supported by a rigid tubular housing. The body forms a cavity filled with a damping fluid and annular dividers define multiple chambers that are concentrically disposed about a central refrigerant gas flow passage. Damping tracks are provided in the dividers to allow fluid flow between the chambers. As refrigerant gas flows through the passage, the pressure/sound pulsations are flattened and smoothed. The resilient walls of the body are designed to bulge inwardly for a maximum 50% restriction. Gas flow orifices of the dividers have substantially the same cross-sectional area as the refrigerant line.
